[0003] The vulcanized valve seat is installed on the valve body. In the traditional technology, the valve seat is directly pressed on the valve body. At present, the valve seat adopts a rubber vulcanized structure. After the valve seat is installed for a long time, the valve seat will be damaged. Loosening or detachment from the valve body, causing the valve to fail

Embodiment Construction
[0011] The specific implementation of the present invention will be described in detail below in conjunction with the drawings and preferred embodiments. Such as figure 1 As shown, an easy-to-install valve seat includes a valve seat body 1 integrally vulcanized and molded by rubber, an inner circumference of the valve seat body is provided with an annular protrusion 2, and the back of the valve seat body is integrally vulcanized and molded with The annular steel ring 3 is provided with rubber protrusions 4 on the outside of the steel ring. The valve seat body and the ring steel ring are provided with concentric valve stem holes 5 for mounting the valve stem. This device improves the traditional rubber valve seat. The rubber valve seat and the ring steel ring are vulcanized together. The outer ring of the rubber valve seat wraps the outside of the ring steel ring, which increases the strength of the valve seat. Rubber bumps are provided on the outside of the ring steel ring, w...

The invention relates to the technical field of valve manufacture, in particular to a convenient-to-mount valve seat. The convenient-to-mount valve seat comprises a valve seat body formed by integral rubber vulcanization, wherein a ring-shaped bulge is formed on the inner-ring circumference of the valve seat body; an annular steel ring is formed at the back of the valve seat body through integral vulcanization; and rubber bulges are arranged outside the steel ring. Compared with the prior art, the convenient-to-mount valve seat has the advantages that a traditional rubber valve seat is improved in the way that the rubber valve seat and the annular steel ring are integrally vulcanized together and the outer ring of the rubber valve seat wraps the outside of the annular steel ring, so that the strength of the valve seat is improved; and meanwhile, the rubber bulges are formed outside the annular steel ring, the friction force between the valve seat and a valve body can be increased to effectively prevent the valve seat from being separated from the valve body, and accordingly, the stability of the valve seat is improved.
Description
Technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a valve seat that is easy to install. Background technique [0002] As we all know, in the field of valve seat manufacturing, one of the rubber molding methods is injection vulcanization molding. In this molding method, the refined rubber material needs to be cut into long strips in advance, and then the long rubber material is injected into the molding die by heating and extrusion to implement vulcanization molding. This injection-type vulcanization molding method can reduce defects and bubbles on rubber products and improve the yield rate. [0003] The vulcanized valve seat is then installed on the valve body. In the traditional technology, the valve seat is directly pressed on the valve body. At present, the valve seat adopts a rubber vulcanized structure. After the valve seat is installed, the valve seat will Loose or detach from the valve body, causing the valve to fa...
